Firmware iOS weighs between 3 and 6 GB - this is a significant burden on your tariff, especially if you have a limited Internet package. Here's how reduce traffic consumption:

If you still decide to update through mobile Internet, monitor your data consumption in real time:

1. Open Settings → Cellular.
2. Scroll down to the Cellular Data Usage section.
3. Click on Current periodto reset the counter before loading.

A critical detail: if the connection is interrupted during the firmware download, the iPhone may become stuck at the "Preparing for update" stage. In this case, only a forced reboot (press and quickly release) will help. Increase volume, then Decrease the volume, hold Side button before the Apple logo appeared).

4. Alternative methods: Internet distribution and public networks

If you don't have a computer, but you have another device with unlimited internet (for example, iPad or Android smartphone), you can use it as Wi-Fi hotspotThis method will trick the system into thinking you are connected to a regular wireless network.

Instructions for Android:

1. Open Settings → Network & Internet → Hotspot & Tethering.

3. On your iPhone, connect to this network and run the update via Settings → General → Software Update.

For iPad or the second iPhone:

2. Connect the main iPhone 11 to the shared network.

⚠️ Note: Some carriers block internet tethering on plans with limited data. If the hotspot doesn't turn on, check your plan's terms or contact support.

Another option is - public Wi-Fi networks in cafes, airports, or shopping centers. However, there are risks:

• 🛡️ SecurityPublic Wi-Fi is vulnerable to man-in-the-middle attacks. Avoid entering your Apple ID password on these networks.
• 🐢 Speed: During rush hour, the speed can drop to 1–2 Mbps, which stretches the download for hours.
• 🚫 Restrictions: Some networks block access to Apple servers (for example, on hotels or corporate networks).

What to do if the iPhone does not see the network being shared?

Make sure that the sharing device is enabled Wi-Fi 2.4 GHz (The iPhone 11 does not support a 5 GHz hotspot.) Also, make sure that a password is set in the hotspot settings (iOS may ignore networks without a password by default).
